purposes only and hold harmless to SAMES KREMLIN. The user is reponsible for the

extracion and conditioning of the painting area where the equipment is used, for working

conditions.

The 1 m / 39.37" distance may be modified if trials carried out by the user deem this

necessary.

• Using the grounding air hose, connect the gun to an air regulator that can supply

at least 3 bar / 43.5 psi.

• Using the fluid hose, connect the gun fluid fitting to the pump. Tighten the fittings

firmly.

Note: In some particulars cases, if the air hose (4) is not conductive, the fluid hose

(3) must be conductive. One of the 2 gun hoses (air or fluid) must be conductive.

7 Storage

Our equipment must be stored in its original packaging.

In case of prolonged storage, it is preferable to carry out preventive maintenance for all

lubricants before start-up.

Storage before installation

• Storage ambient temperature 0 / +50 °C (32° F / 122° F).

• Protect the complete unit from dust/dirt, water/condensation, moisture, vibration

and shock.

• Do not remove the packaging until just before assembly.

Storage after installation

• Protect the unit from dust/dirt, water/condensation, moisture and shock.

8 Start-up

• Assemble the aircap on the gun by positioning it according to the desired spray

orientation.

• Open at the maximum the air needles.

• Open the fluid needle as far as i twill go without a stop.

• Connect the air hose.

• Assemble the cup or connect the fluid hose.

• Pull the trigger and check that the air is circulating normally.

9 Adjustments

This professional spray gun features 3 controls :

Spraying fineness

• Air is fed by the central air. The air is adjusted by means of the air regulator

mounted upstream of the gun on the network and more precisely by means of

the knob at the bottom of the gun handle on some manual guns.

Fan width

• Fan width is adjusted by using the knurled knob. It controls the air going to the

horns on the aircap. In this way, the air is controlled through the fanned air outlets

and allows the fan to change from flat (wide open) to round (closed).

Fluid output

• Having selected the proper fluid nozzle / needle assembly and the fluid pressure,

it is possible to:

• Further control the output by changing the travel of the needle (using the needle

stop knob).

• Optimal set up is usually obtained when the fluid needle is completely open.

When this needle is nearly closed, a constant flow of fluid cannot be

guaranteed.

10 Gun handling

When assembling the aircap on the gun, hold it vertically in order to correctly align the

aircap before screwing the aircap ring.

Proper position

Improper position

• Keep the gun perpendicular to the surface to be painted.

• Avoid working with the wrist.

• Do not forget that crossed sweeps cannot correct irregularities. Spraying from a

stationary gun will not give you even coverage.

• Start the pass and trigger just before the leading edge. Release the trigger

before the pass ends, just after the trailing edge of the object.

• Make sure that overlapping from the passes is even.

11 Maintenance

11.1 Preventive maintenance

Daily

• Check groundings.

• Clean the outside of the spray nozzle with a soft brush and solvent.

• Flush the spray gun.

• When the spraying system will not be used for an extended period of time, take

off the nozzle and immerse it in s solvent filled container.

Weekly

• Check leakage from the fittings

Monthly

• Check hoses.

• Operate the valves.

• Remove the air valve, clean it if necessary. Grease it as well as the spring before

assembling.

• Remove the needle as well as the rear line and the complete air valve.

• Clean the parts and grease them before assembling.

Annual

• Change the air valve. Grease the air valve as well as the spring, before

assembling.

• Remove the gun.

• Clean the parts.

• Change the seals and any defective parts.

• Grease them before assembling (refer to seal and servicing kits).

Note: Frequencies are given as an estimate. They must be adapted by the

maintenance service of the user for every installation depending on the fluid, the

workload and the working pressure.

12 Assembly - Disassembly

Before removing a component of the gun, some precautions have to be taken:

• Shut off the fluid pressure,

• Empty out the paint inside the cup or the receiver and clean it,

• Fill the cup or the receiver with cleaning solvent,

• Take off the gun spraying air cap,

• Shut off the gun supply air pressure,

• Adjust fluid pressure to 0.5 bar / 7.25 psi and let the solvent circulate,

• Shut off the fluid pressure,

• Remove the part to be cleaned or changed.

Before reassembling the different components, some precautions must be taken:

• Clean all the parts with the appropriate cleaning solvent and a brush.

• Install new seals if it is necessary after having lubricated them with PTFE grease.

• Install new parts if it is necessary.

13 Assembly errors

The use of improper replacement or defective parts may result in hazards to personnel,

damage, malfunction or general shutdown of the equipment.

14 Troubleshooting

Distorted

spray

Slightly unscrew the aircap retaining ring and rotate the

aircap by one half turn. If the defect is reversed, one of the

lateral air holes is plugged up or deformed. Clean the gun

aircap with solvent and unclog the air holes with

compressed air. If the problem is not resolved, it means that

the fluid nozzle is damaged.

Displaced

spray

This comes from a defect in the central fan. Clean the

aircap and the fluid nozzle. Make sure that:

• the aircap is correctly centered on the nozzle,

• the nozzle is not too big for the needle,

• When work is done with a large needle opening and the

needle almost closed, the spray pattern is not even in all

directions.

Fragmented

pattern

The fan air pressure is too high at the holes in the air cap

horns:

• turn the fan air

control clockwise to reduce the fan air

pressure,

• increase the paint output.

Fan too thick

in the center

This is the reverse of the above defect:

• the paint output is too high for the selected air pressure :

• increase the spraying air pressure and reduce

the paint

output.

• if the paint is too thick, dilute it.

Intermittent

spray pattern

An air inlet in the paint circuit creates an intermittent

pattern when:

• the paint cup is nearly empty,

• when the nozzle is not tightened on its seat: clamp it.

If the problem persists, remove the nozzle and clean it.

•

Check that the seat and the cone are not damaged,

remove the nozzle and clamp it.

• Check that: the cup cover air hole is not blocked and the

paint is homogeneous and fluid enough (use the viscosity

cup).

•

Check that the ‘pressure’ gun is not being used with a

‘suction’ cup.

Trouble Cause Solution

No fluid out of the gun • Clogged nozzle

• Cut the pressure on

the pump.

Depressurize the hoses.

• Remove and clean

the nozzle with solvent

by means of the brush.

• Check the seal

condition.

Pattern width narrows

during reversing phase of

the pump

• Air trapped in the fluid

circuit

• Check connections

and suction hose

quality.

• Viscosity too high

• Reduce viscosity.

Aircap becomes dirty

frequently

• Too much atomizing

air

• Reduce air pressure.

Fluid seeping from the air

holes of the aircap

• Defective nozzle seal

• Replace it.

• Nozzle loose

• Tighten it.

Fluid leak at the packing • Packing is worn

• Tighten up the packing

holder without

blocking the needle.

• If there is still a leak,

replace the packing

and the needle.

Fluid leak at the front part

of the gun, trigger released

• Impurities in the paint • Trigger the gun 3 or 4

times.

• Needle worn or/and

nozzle worn

• Replace needle

or/and nozzle.

Air leak at the valve • Valve worn • Change the valve.

Permanent air leak at the

gun aircap when the

trigger is released

• Friction on the needle • Remove the trigger

and check that the

needle slides freely.

• Valve worn • Replace the valve.
